Decoding SKF 2317 KM/C3
- 23Series
- Self-aligning ball bearings, 23 series. Series differ in outside diameter and width even when the bore is the same.
- 17Bore
- Bore 85 mm (17 × 5).
- KM/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
2317 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 2317 KM/C3 measures 85 mm across the bore and 180 mm across the outside diameter; its width is 60 mm (85 x 180 x 60 mm).

SKF self-aligning ball bearings are double-row bearings with a spherical raceway in the outer ring. This design lets the bearing align itself and compensate for angular misalignment between shaft and housing, which is useful when shaft deflection or mounting errors cannot be avoided. MR Industrial Accessories supplies this line to customers across the United States and Latin America.
The part number tells you the series and the features. Take 1322 KM/C3: series 13, tapered bore (K), lubrication groove and hole (M), and C3 internal clearance. In 2220 KM/C3, the 22 prefix indicates a series with higher load capacity. The C3 suffix means radial clearance is greater than standard, which helps when fits are tight or temperature differences exist. Reading these codes correctly is the first step in choosing the right bearing.
These bearings suit equipment where perfect alignment is hard to maintain: conveyors, industrial fans, centrifugal pumps, textile and agricultural machinery. They are also found in kiln and dryer rollers, where thermal expansion creates changing misalignment. The self-aligning ability reduces wear and extends service life in assemblies with long shafts or separate housings.
Selection depends on radial and axial load, speed, and the operating environment. A tapered bore (K) needs a suitable adapter sleeve to achieve a controlled interference fit. C3 clearance is recommended for high-temperature operation or tight shaft fits. Choose lubrication based on temperature and speed; for high speeds, a medium-consistency grease works well. Even though the bearing self-aligns, initial alignment must stay within permissible limits to avoid extra stress.
For equivalents, SKF self-aligning ball bearings can be interchanged with other brands that follow the same dimensional and suffix designation. For example, an SKF 2220 KM/C3 matches bearings from other manufacturers with identical nomenclature, as long as tolerances and specified clearance are respected. Always verify the complete code, because small suffix changes affect sealing or lubrication. Consult a specialist to confirm interchangeability before replacing.

Frequently asked questions
- SKF 2317 KM/C3 bearing: what are its dimensions?
- SKF 2317 KM/C3 measures 85 mm across the bore and 180 mm across the outside diameter; its width is 60 mm (85 x 180 x 60 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 2317.
- What does the KM suffix mean on an SKF bearing?
- The KM suffix indicates a lubrication groove and hole in the outer ring. This makes relubrication easier and improves access for periodic maintenance.
- What is the C3 clearance for in these bearings?
- C3 is a radial clearance greater than normal. It is used when the bearing runs at high temperature or with interference fits, to prevent thermal expansion from eliminating clearance and damaging the bearing.
- Can I replace an SKF bearing with another brand?
- Yes, if the dimensional designation and suffixes match. Verify the complete code and consult a specialist to ensure interchangeability and performance.
